A PDF document can contain multiple pages with different text content, images, or other objects. Occasionally, users may need to delete certain pages with incorrectly drawn objects or pages that are irrelevant to the topic of the document. This article will demonstrate how to programmatically delete/remove pages from an existing PDF document using Spire.PDF for .NET.

Delete/Remove Pages from PDF

• Create a PdfDocument object.
• Load a sample PDF document using PdfDocument.LoadFromFile() method.
• Get the pages in the PDF document using PdfDocument.Pages property.
• Delete a specified page by index using PdfPageCollection.RemoveAt(int index)method.
• Save the document to another file using PdfDocument.SaveToFile() method.

using Spire.Pdf;

namespace RemovePage
{
    class Program
    {
        static void Main(string[] args)
        {
            //Create a PdfDocument object
            PdfDocument document = new PdfDocument();

            //Load a sample PDF document
            document.LoadFromFile(@"E:\Files\input.pdf");

            //Remove the second page
            document.Pages.RemoveAt(1);

            //Save the result document
            document.SaveToFile("RemovePDFPage.pdf");
        }
    }
}

Imports Spire.Pdf

Namespace RemovePage
    Class Program
        Private Shared Sub Main(ByVal args As String())

            'Create a PdfDocument object
            Dim document As PdfDocument = New PdfDocument()

            'Load a sample PDF document
            document.LoadFromFile("E:\Files\input.pdf")

            'Remove the second page
            document.Pages.RemoveAt(1)

            'Save the result document

Table Layout decides how the table displays in PDF page. People always set PDF table layout in order to let the table perfectly fit PDF page according to their own like. In this section, I will introduce a solution to set table layout in PDF via this .NET PDF component Spire.PDF for .NET with C#, VB.NET. First let us view the target PDF file as below picture:

In Spire.PDF for .NET, there is a class called: Spire.Pdf.Tables.PdfTableLayoutFormat. By using this class, we can set table layout type and break type. Here Spire.PDF provided two layout types: Paginate and OnePage and two break type: FitElement and Fit Page. When you set the break type to be FitElement, PDF table will display according to the table length, while for FitPage choice, the table will automatically fit the PDF to every page ignoring table length.

Here let us see this method: PdfLayoutResult.Draw(PdfPageBase page, PointF location, PdfTextLayout format).There are three parameters passed. The first parameter determines the page size and margin. By setting the second parameter, we can set the horizontal and vertical distance between the table and PDF margin. While the last parameter is the table layout we just set. Obviously, we can set table layout by calling this method directly.

Now, you can download Spire.PDF for .NET and start table layout task by below key code:

table.BeginRowLayout += new BeginRowLayoutEventHandler(table_BeginRowLayout);
            PdfTableLayoutFormat tableLayout = new PdfTableLayoutFormat();
            tableLayout.Break = PdfLayoutBreakType.FitElement;
            tableLayout.Layout = PdfLayoutType.Paginate;
            PdfLayoutResult result = table.Draw(page, new PointF(0, y), tableLayout);
            y = result.Bounds.Bottom + 5;

table.BeginRowLayout += New BeginRowLayoutEventHandler(table_BeginRowLayout)
Dim tableLayout As New PdfTableLayoutFormat()
tableLayout.Break = PdfLayoutBreakType.FitElement
tableLayout.Layout = PdfLayoutType.Paginate
Dim result As PdfLayoutResult = table.Draw(page, New PointF(0, y), tableLayout)
y = result.Bounds.Bottom + 5
